Answer:

b = 7 $\sqrt{3}$

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for b

and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , thus

tan30° = $\frac{opposite}{adjacent}$ = $\frac{7}{b}$ and

$\frac{7}{b}$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

b = 7 $\sqrt{3}$

Principal=2000,R=12percent,Time=2years and 6 months.

almond37 [142]

Principal=P=2000
Rate of interest=12%
Time=2years and 6months=2.5years
Interest=I

$\boxed{\sf I=\dfrac{PRT}{100}}$

$\\ \sf\longmapsto I=\dfrac{2000(12)(2.5)}{100}$

$\\ \sf\longmapsto I=\dfrac{24000(2.5)}{100}$

$\\ \sf\longmapsto I=\dfrac{60000}{100}$

$\\ \sf\longmapsto I=600$
